Months after the events of Black Heart, Nasira is off to attend the vampire Senate in Tokyo, leaving Annie alone with three rules: stay behind, don't have guests, and be good. Annie violates this immediately by inviting over her brother, Asher, and traveling to Tokyo to surprise Nasira. But, it's Annie who's surprised: she arrives in time to witness a failed assassination attempt on her lover! With Nasira in a coma, Annie must enter the world of vampire intrigue and Japanese mythology, aided by her brother (not so much) and a timid doujinshi author (more than you'd think), and figure out who tried to kill Nasira before they come back to finish the job!
